WITHDRAWAL: fetchmail 6.4.22.rc1 release candidate #1

Greetings,

I am withdrawing 6.4.22.rc1 and ask that nobody installs it anew if IMAP
fetches are desired.  Setups that purely use POP3 seem fine for now, and
if your setup can fetch mail from all your configurations, you need not
downgrade.

Sorry about this, but that is why there are release candidates, some
turn out to be unworthy of promotion to a release.

I am moving 6.4.22.rc1 around on sourceforge from branch_6.4/ to
OldFiles/ so that people missing this announcement don't find it at the
place announced earlier.

Withdrawal reason: I received and confirmed a regression report against
fetchmail's IMAP client, and 6.4.22.rc1 misidentifies IMAP protocol
versions and in many situations tries IMAP4 commands on IMAP2 and
IMAP4rev1 servers, which leads to poll errors without any mail
downloaded.  This is a side effect from the "reset session data", not
covered in my testing scenarios.
